Majority of people use their mobile devices these days to browse the Internet. Installing an ad blocker on your iPhone is a significantly bigger challenge than on desktop.
Firefox on Android supports it without any issue. That would cover a significant enough segment of the population that it might encourage actual change in the industry if people started moving to that platform.
Browser extensions for iOS are bundled with Apps. It’s not “a significantly bigger challenge” to install an app than a Chrome extension.
It’s becoming easier on iPhone (even uBlock origini is now available, if only the lite version), which is nice because internet is becoming more and more unusable without them.
AdGuard installs through the App Store and integrates seamlessly with Safari. It's not as perfect as some of the desktop class adblockers, but it's free and can be up and running in a couple minutes.
If you're on Android, Firefox supports many full desktop extensions, including uBlock Origin.
There have been mobile Safari ad blockers for 10 years now, free or paid, and many of them can now be unified with desktop Safari. Many alternative iOS browsers include ad blocking directly, since they can't use the Safari plugins (despite all being powered by WebKit).
1Blocker has been great for me and includes blocking of many/most (almost all?) in-app trackers too.
Can't speak for IOS but for android users I highly recommend Firefox for android, since you can install ublock origin within it. Let's be real, browsing the modern internet is downright impossible without it today.
How is installing uBlock Origin Lite on iPhone a big challenge? Installing it on my SO's device was quite trivial.
Not really - I use Brave browser on iPhone, a simple app install, and it blocks ads extremely well, even on YouTube and Instagram.
Brave has served me well in this regard. I don't even get ads on YouTube on mobile.
My pihole does a good enough job with phones. I know google wants to close this (hence pushing things like DoH)
Last time I tried firefox on the iphone it was rubbish compared with safari. Same with some ad blocking app I had back in the day
Not anymore. You can just find one on the app store and install it, almost exactly the same as you do in a browser's extension "store". It won't be as good as uBlock but it certainly works fine even in Safari.
Use Firefox/Fennec which allow you to install a variety of the add-ons you can install on the desktop version such as UBO, Stylus, ViolentMonkey, Bitwarden, SponsorBlock, etc... or install Brave which comes with adblock by default. As for iPhone, you can install Brave which has adblock, I don't think Firefox has add-ons in that version though, not sure.
